The 25 best fast-food chains

25. Jet's Pizza

Headquarters: Sterling Heights, Michigan

US sales in 2016: $368 million

Number of US locations: 404

Customer satisfaction rank: 24

Value rank: 35

Brothers Eugene and John Letts opened the first Jet's Pizza restaurant in Michigan in 1978 and since then, it's spread to 18 different states across the US.

Jet's claims not to scrimp on ingredients. And its pizzas aren't dirt cheap. On average, customers can expect to spend $8.05 on a meal at the chain. Its signature style, the deep-dish square pizza, comes in many varieties or customers can choose to create their own from scratch

24. Jamba Juice

Founded in 1990 in a California beach town, Jamba Juice was years ahead of today's ubiquitous green smoothie and healthy living trends and remained a favorite for loyal customers over the years.

The chain's menu has expanded sine then, now offering Greek yogurt or acai berry bowls with soy milk. There's also plenty of new fruit and vegetable smoothies.

Headquarters: Chicago, Illinois

US sales in 2016: $446 million

Number of US locations: 454

Customer satisfaction rank: 25

Value rank: 16

When Potbelly opened in 1977, it was an antique shop. The young couple who ran it decided they wanted to serve lunch to their customers and the store evolved into a local lunch spot. In 1996, entrepreneur Bryant Keil bought Potbelly and turned it into a franchise; he stepped down as CEO in 2008 and is no longer involved.

Today, not only do all the Potbelly stores serve sandwiches and fresh cookies, but each location has its own potbelly stove.

22. Jimmy John's Gourmet Sandwiches

Headquarters: Champaign, Illinois

US sales in 2016: $2.22 billion

Number of US locations:2,620

Customer satisfaction rank: 30

Value rank: 15

At Jimmy John's, customers can't get enough of the chain's signature subs and "freaky fast" delivery service. Jimmy John Liautaud opened the first shop back in 1983 to avoid pressure from his father to perform a stint in the Army. Papa Liautaud lent him $25,000, and if the restaurant turned a profit the first year he wouldn't have to enlist. Sure enough, the gourmet sub business took off and he slowly expanded across the country — it now has the most amount of franchises in our top 25 list.

Jimmy John's franchises commit to sustainability by partnering with suppliers who reach high standards of sustainable and ethical food practices. The chain also employs local businesses to build and maintain each JJ's store.

US sales in 2016: $760 million

Number of US restaurants: 683

This Canadian chain, known for its coffee and donuts, has also become a favorite in the US. It was set up in 1964 by its namesake Tim Horton, a former National Hockey League legend in Canada.

Horton started off by selling coffee and donuts, which cost 10 cents each, but by the '80s he added muffins, cakes, soups, and chili into the mix. These are now staples on the menu.

17. McAlister's Deli

Number of US locations:1,284

Customer satisfaction rank: 14

The cult favorite started in Washington, DC, in 1986 when former bond trader Jerry Murrell and his family opened a burger joint — named after Murrell and his four sons — with the goal of cooking hamburgers and fries using the best quality ingredients.

The chain is off-limits to those with peanut allergies, as all fries are cooked in peanut oil and there are barrels of old-fashioned peanuts lining each shop's dining area.

Jersey Mike's is now known for its handcrafted subs loaded with high-quality ingredients. In 2016, Nation's Restaurant News announced that it was the fastest growing restaurant chain in the US.

9. Culver's

Headquarters: Prairie du Sac, Wisconsin

US sales in 2016: $1.3 billion

Number of US restaurants: 605

Customer satisfaction rank: 23

Value rank: 29

At Culver's, diners can expect to spend a little more than they would at a run-of-the-mill burger joint, with average orders totaling around $10, according to Technomic. But it might just be worth it for the chain's frozen custard and ButterBurgers, the signature burger that gets its name from the glaze of butter that coats the bun.

8. Jason's Deli

Headquarters: Beaumont, Texas

US sales in 2016: $702 million

Number of US restaurants: 260

Customer satisfaction rank: 9

Value rank: 12

Nutrition is a priority at Jason's Deli, which serves sandwiches, salads, pastas, soups, and desserts. It has eliminated artificial trans fat, most artificial MSG, and all artificial colors, dyes, and flavors from its food over the past 10 years. It even claims that its soft-serve is made with 100% natural ingredients.

7. Papa Murphy's Pizza

Headquarters: Vancouver, Washington

US sales in 2016: $885 million

Number of US locations: 1,537

Customer satisfaction rank: 7

Value rank: 2

This pizza franchise started in 1995 after the merger of two pizzerias, Papa Aldo's and Murphy's Pizza. Its pies are "take and bake," meaning they are made to order and cooked in the customer's oven at home.

Customers can pick from the signature pies like Pepperoni and Hawaiian, or they can create their own and choose the type of dough, sauce, and toppings. Papa Murphy's scores top marks for customer satisfaction on value, coming in at second place in the total list of 25 restaurants.

6. Pollo Campero

With only 68 stores, Pollo Campero is by far the smallest chain on the list. But diners adore the casual chicken spot, touting it as a solid value.

Pollo Campero, initially founded in Guatemala in 1971, stands out from other "better chicken" chains, such as Wingstop and Raising Cane's, for its authentic Latin flavors and impeccable service — meals are served on real plates with real silverware.

5. Krispy Kreme

Headquarters: Winston-Salem, North Carolina

US sales in 2016: $758 million

Number of US restaurants: 307

Customer satisfaction rank: 6

Value rank: 17

In 1937, Krispy Kreme founder Vernon Rudolph used a recipe given to him by a New Orleans chef so that he could make and sell doughnuts to local grocery stores. As the fresh-baked donut smell wafted into the streets, customers began requesting to purchase the delicacies directly, so Rudolph cut a hole in the wall to open his first retail location.

In October 2015, the chain opened a new store in North Carolina which resembled a coffee shop, Business Insider reported. Six months later, it was bought by JAB, the parent company of coffee brands including Caribou Coffee, Peet's Coffee and Tea, and Keurig Green Mountain, for around $1.35 million.

4. Whataburger

Headquarters: San Antonio, Texas

US sales in 2016: $2.2 billion

Number of US locations: 806

Customer satisfaction rank: 17

Value rank: 11

Whataburger founder Harmon Dobson's goal was to create a burger so big that customers would have to use both hands to hold it. It would be so good that at first bite they would declare, "What a burger!" Thus, in 1950, Whataburger was born.

What started off as a burger stand, almost 70 years ago, now has 700 restaurants in the US. Although it lost out to In-N-Out Burger in Business Insider's taste comparison, it's still a favorite of many in the south.

3. Chick-fil-A

Headquarters: Atlanta, Georgia

US sales in 2016: $6.7 billion

Number of US restaurants: 2,062

Customer satisfaction rank: 2

Value rank: 3

This Southern favorite is the largest food chain on our list and comes in first place for total sales in 2016.

The fried-chicken chain diversified its menu last year, adding a kale and broccolini salad, a premium coffee line, new sauces, and a barbecue-bacon sandwich in an effort to take on competitors. If you want to know what's best to order, check out Business Insider's guide.

1. In-N-Out Burger

In-N-Out Burger scores highest on customer satisfaction and value, making it the winner overall.

California's first drive-thru hamburger stand, In-N-Out Burger first opened in 1948. Nearly seven decades later, the menu remains simple, offering only five items. But loyal customers know that if they want to expand their options, they can order off the not-so-secret menu — it features items such as a protein style burger and grilled cheese.

In-N-Out can only be found on the West Coast, but there's a good reason for that. Since the chain prides itself on serving top-notch ingredients free of additives or preservatives, all stores must be within 300 miles of the distribution facilities. Sorry, East Coasters.

BACK TO SLIDE

Roark's offer is at a 34 percent premium to the stock price on Nov. 13, the last trading day before media reports that private equity firm had made an offer of more than $150 per share.

The deal is the latest in a flurry of restaurant takeovers by private equity firms. In October, casual dining chain Ruby Tuesday was bought by NRD Capital for about $335 million, while Luxembourg-based JAB Holdings took U.S. food chains Panera Bread and Krispy Kreme Doughnuts private over the last two years.

Including debt, the Buffalo Wild Wings deal is valued at about $2.9 billion.

Activist hedge fund Marcato Capital Management, which had put pressure on the company to pursue strategies to boost its stock price, said it would vote for the deal.

Marcato, which owns 6.4 percent of Buffalo Wild Wings, won three seats on the company's board in June after a sustained campaign criticizing its performance under Chief Executive Sally Smith.

Following the deal close, expected during the first quarter of 2018, Buffalo Wild Wings will become a privately held unit of Arby's and operate as an independent brand.
